Stomach

A digestive organ that also releases hormonal signals, including gastrin. A signal’s site of production is distinct from its target.

Receptor location — biological context

A receptor in an organ does not prove that this compound reaches or affects that organ.

GLP1R
Homo sapiens · non-human primates
The tissue study detected GLP1R in parietal cells and smooth muscle cells in the outer muscle layer of the stomach. Location alone does not measure a molecule’s effect on gastric emptying.
